  Catalytic Geminal Difluorination of Styrenes for the Construction of Fluorine-rich Bioisosteres

  摘要：

  A geminal difluorination of alkenes based on I(I)/I(III) catalysis is disclosed, which is compatible with a range of electronically and substitutionally diverse styrenes (27 examples, up to 89% yield). Employing inexpensive p-Toll as the organocatalyst, turnover is enabled by Selectfluor-mediated oxidation to generate the ArIF2 species in situ. Extension to include alpha-substituted styrenes bearing fluorine-containing groups is disclosed and provides an expansive platform for the generation of fluorine-rich architectures.

  Pd‐catalyzed Hiyama vinylation reaction of non‐activated aryl chlorides and bromides under mild conditions was developed. The use of efficient vinyl donors and electron‐rich sterically hindered phosphine ligands was critical for the success of the reaction. The products of this transformation can be used for Am/Cm separation, an important challenge in nuclear fuel reprocessing. The substituent effect

  The use of alkenyl arenes as dipolarophiles in the catalytic asymmetric 1,3‐dipolar cycloaddition of azomethine ylides is reported. Under appropriate reaction conditions with a CuI or AgI catalyst either the exo or the endo adduct was obtained with high stereoselectivity. This process provides efficient access to highly enantiomerically enriched 4‐aryl proline derivatives. The observed results are

  据报道，烯基芳烃在偶氮甲亚胺的催化不对称1,3-偶极环加成反应中用作双极性亲和剂。在适当的反应条件下，用Cu I或Ag I催化剂以高的立体选择性获得外型或内型加合物。此过程可有效获取高度对映体富集的4-芳基脯氨酸衍生物。观察到的结果与1,3-偶极的一个前手性面的阻滞，以及亲电性向亲双性分子的末端碳原子的有效传递是兼容的。这种极化导致从协调机制到逐步机制的转变。
